    • Blade located on top of foot to increase kick efficiency by transferring more power to the blade.
    • Made of buoyant, closed-cell EVA foam to force the leg to work the downkick while increasing ankle flexibility.
    • Soft and comfortable fit.

  • 8/13/2013 Love these!

    rating star By PP

    I use these for lap swimming at our local pool.  They are so light that they float on the surface while I am swimming and cause me to keep my legs and body straighter and thus make for a better workout. they seem to strengthen my legs and hip area.  I wear a ladies size 8 and i bought an XS, which was just perfect.
    I look forward to taking them with me when i travel, because they are so light.

  • 1/5/2012 Sizing note

    rating star By Lynne

    Love this fin in the water and light to lug around. I wear a 7.5 womens shoe so an XS would have been more appropriate.  I ordered S based on charts, which works fine but they are roomy.

  • 9/10/2013 Interesting

    rating star By Craig

    I use these for kicking drills and some intervals. They are great for swimming butterfly and stay on well.  They are large for a fin this stiff and really work you legs. They are very bouyant and interfere with my freestyle body position unless I am sprinting. So they are not so good for distance swimming. Great for sprints.

  • 8/30/2013 Awesome

    rating star By Cathy J C.

    These are the most awesome swim fins. I have tried several types of the rubber fins and they have been way to heavy for me. Because of nerve damage from a back injury my legs muscles are weak and the heavier fins just don't work. These are so light and buoyant that your feet stay right up near the surface and I can kick very easily with them.
    I ordered a size large as one of the other reviewers commented that she had size 11 feet (me too) and they fit perfectly. Love, love, love them.

    Love these fins but a medium for a women size 9 is very roomy.  Still works though.  Fins really give your legs a better workout.

    rating star By Lisa B.

    I have size 7.5 women's size feet and my feet are very narrow.  Even the extra small size of these fins were huge on my feet.  My feet swam in them so I didn't.  I had to return them.

  • 10/1/2014 Extremely lightweight. True to size.

    rating star By Geneva

    I decided to try these flippers after undergoing two knee surgeries this year.  I kept reading how lightweight these were and I thought that it would be good for my knee.  You know, not quite so heavy on the knees as other flippers can be.  So I tried them.  And I really like them!  I don't have to use the flipper booties that I always have to wear with heavier flippers.  And they don't cause blisters.  They fit true to size for me.  Great flippers for a great price!  A+A+A+

    rating star By Phoebe F.

    Be aware that the sizes don't always apply.  My shoe size is 9 which requires a SMALL fin size but I had to return the first shipment as the Small was much too tight.  I exchanged them for a MEDIUM which is fine.  It helps to smear a small amount of soap in the fins to allow for a more comfortable foot insertion.

  • 10/1/2013 Although I used the size chart, I could not get these fins on easily.

    rating star By Linda T.

    Am going to order a larger size and try them.   They are lightweight and I think I would enjoy if I can get in a size that slips over my heels without so much trouble.

  • 9/10/2013 Don't waste your money!

    rating star By Shirley I.

    I ordered these fins 3 times to get a pair that was comfortable around the ankle and did not dig into the bottom of my foot.  When I finally tried them out they wanted to float so much that they literally slap the water as you kick your feet!  I also felt like it took more effort to swim.  I was very disappointed in these.
